Sara Pellet Fire Install.

This install was a little tricky, but we pulled it off!
Installation of the base into the purpose built wall. As you can see, the flue is offset, idealy we would have prefered a straight flue install, but due to the architects drawings, and that directly above is the middle of the master bedroom, it had to go here.

This is the flue passing through the wall, and going up through the second story floor. Later this was closed in with shelving.

Normally we would install the fire after the rooms are finished, but the customer wanted it in first. This is the flue passing through the upstairs walk in wardrobe.

The fire mounted onto its base.

Side view.

The exhaust is just visable to the left of the solar panels.

We left the plastic on the stainless steel fascia because there is a brick wall to be built around the fire to close the wall in, I have seen it, when it was completed, but I didn't have my camera. It looked awesome, and more important, the customer was very happy.

Replacing A Woodfire Cowl.

The customer was complaining about smoke coming out of the fireplace.
This cowl wasn't connecting with the flue, because the legs holding the cowl in position, had been bent down.
New cowl installed correctly, no gap for the weather to get in.

The smoking problem was caused by the cowl not being connected to the top of the flue, this prevents the flue from drawing properly.

Stihl MS660 Cylinder Reassembly.

Customer said that his Stihl MS660 had no power, it was siezed! Pressure test revealed air leak through the clutch side, main bearing seal. The ring land had broken out of the front of the piston, the rings snapped, chipping the chrome above the exhaust port and embedding the rings into the top of the cylinder.
The Stihl MS660 has been cleaned, a new cylinder gasket installed, new piston installed, new gudgeon bearing installed and is now ready for the cylinder to be installed.

A piston block and ring compressor fitted.

Piston installed into cylinder, I have pre-oiled the lip on the intake manifold, to ease installation. I have also put the screws with loctite added to the threads, into the cylinder, I find it easier than trying to install them after.

Intake manifold installed and cylinder torqued down.

Muffler installed, using loctite on the screw threads.

Top cover, plug and filter cover installed.

Starter installed.

Ready to tune.

MTD Wouldn't Stay In Gear.

This is a gearbox out of an MTD ride on lawnmower, which was slipping out of the forward gear. What I found was damage to the leading edges of the forward gear and the clutch collar. The clutch collar is reversable, so I turned it over, but the gear had to be replaced.
Parts cleaned and ready for reassembly.

Reel Mower Catcher Repair

This catcher had been rubbing against a wall, wearing the seam away. It's a Lawnmaster catcher, made of thin aluminium. I decided to repair it with strips of stainless steel and rivets.
Before.
After, much cheaper than replacement and stronger.

Chainsaw Handlebar Repair

I also repair chainsaw handlebars, whether it's broken, bent or has part of it worn away. In this case, it's a handlebar off a Stihl MS460, which had broken through the top mount hole.
In this case I have completed the repair.

You can see that I have welded a piece of flat onto the handlebar, to strengthen, then drilled the mount holes oversize to allow the original screws to be reinstalled. I have had great success with this type of repair.

Husqvarna Top Spike Mount Repair

This is a job I did for a local Chainsaw Shop. The top spike mount had been flogged out, and there was a broken off screw deep in the mount.

Before, the top spike mount is totally flogged out.

Here I have ground the mount out, and removed was left of the broken screw.

Front view.

Here I have built the crancase back up with magnesium, in preparation for finishing.

Ready for drilling and retapping, the shop that I did this for, wanted to complete that part.

Dosko Stump Grinder modification

This is a modification I did on a Dosko Stump Grinder, originally there was a cable that engaged the cutting wheel, but because the cable siezes and the cable is not readily available in NZ, not to mention the price, I designed and installed this linkage system. Although this was not that cheap to do, the customer was very happy, with no problems after 2 years of heavy use.
You can see the linkage running down the handle from the control lever, pivoting off the handle pivot, to limit any adjustment when changing handle position. Any adjustment is easily done by twisting the knob on the top of the lever.

This is the second pivot, which travels down to the transmission.

This is a closer look at the first pivot. As you can see, I was giving the engine an oil change.

Repairing Stihl MS660 Top Spike Mount.

This is not a common problem with Stihl MS660s, but happens occasionally when the operater allows the screws to vibrate loose (caused by operaters lack of chain/sprocket maintainance) & pull out through the housing.

This is a broken out spike mount on a Stihl MS660.
Here I have ground out & magnesium welded the housing, ready to be drilled to remount spike.

I have drilled ready for screw to be installed.


Masport I3000 Install

This is Masport I3000 that we installed late last year, as you can see the brick chimney has been taken down to the top of the fireplace. This was done because the installers of the previous fire had removed too many bricks, weakening the structure. We then installed a double cased flue system, and flashed over the hole that the brick chimney left.


You can see that we have installed a top panel on the fire fascia, this was to cover the hole that was left above the fascia, also there is a mantleshield installed to the underside of the mantle to protect it from prolonged high temperatures.
