OutdoorKing Repair Forum Forums Repairs and Maintenance Questions on Walk Behind Lawn Mower Frames Question On Scott Bonnar Cylinder Mowers Novice Owner - Scott Bonnar 45, 20inch

Steve, thank you for posting these tips for other restorers. Your mower restorations are the most impressive I have seen, and are an inspiration to others. Both your techniques and your execution are remarkable - any time you are willing to pass on a hint to the members here, I think you'll find people listening with close attention.

Hi Craig, here are the pics of the decals as applied to the last model (aka "Mark2") Scott Bonnar Model 45.


Handle bar cover decal


Catcher and chain case cover decal

Hi Grumpy, I totally agree with you there, I think Steve's attention to detail is absolutely brilliant and the end result of his restorations is better than factory finish, and a real credit to him. Any hints he can pass on will be greatly appreciated by all members.

Agreed Grumpy and Deejay,

Deviosi has set the standard with absolutely brilliant restorations! I have in fact printed off all of his work for ideas, tips and indeed inspiration! Throughout stages of my restoration i have thought... damm, how did he get this so neat and perfect.. great attention to detail!!!

On another note.. I have just finished rebuilding my catcher. Not quite as good as Deviosi's but I'm ok with the end result. will post some pics soon.. The engine is painted and the frame is ready for final coat. Handle bars and accessories are back from the electroplaters. Awaiting a few spares from turf machinery, my local bearing shop and a metal supplier for my front roller and finally put it all back together..

Craig, did you get hold of some decals?? I could use a few myself, for front of catcher, chain cover & handlebars if I could find who makes them.
Thanks- Ross

Not yet Ross, working on that at the moment, Devoisi did say he had a contact though.. Maybe if you get a hold of him? I would be happy to know aswell! Other wise I'm going to get someone local - sticker maker to make some up.. I'll give him the design. Prioity is to get the thing back together first! Lawn needs a mow!.

A guy from Adelaide on Ebay is selling some SB decals. I have purchased the green pentagon for the catcher and round red decal for the handle bars to suit the early 1980 Model SB45's. Im not sure if he does the chain case cover though.. So if Anyone is interested have a look.
Cheers, Craig.

His user name on Ebay is silensmessor He watch's this board too.

Paint is on... Just waiting for two rear drum bearings and a new front roller.. Here are some pics.

Some more..

Decals...

Old Catcher, I cut the guts out as it was rusted, had dents and holes all through it. I rivited a new piece of .8 mm galvanised sheet steel in.

New catcher after many hours..

New Vs Old...

The Green ended up being a bit deep and maybe a bit too blue but it'll do me.. The red is pretty spot on.. The rear main roller is painted white, I understand it won't look like that forever but when the paint wears off the high spots it should look ok with white grooves anyway. I needed to paint the rear roller as surface rust would have appeared quickly after cleaning it back to bare metal. It was etch primed and painted with rustproof white paint (Galmet). I did not want to paint it green as it just felt like too much, I wanted to break it up a little. The green and red colours were just eye matched.. All painting done with spray gun. Will post some more pics once I start rebuilding.
Cheers, Craig.

Awesome job, cannot wait to see it finished

Look like it came up nice

Nice Craig. Will look better than a newie once assembled..

My on a nice resto thus far, Craig.....Don't know about the white rear roller tho..Lol!

I have started to reassemble after painting though have a small query regarding the rear main roller..

With regards to the rear main bearing housings (2 off) one has three holes (no adjustment) and the other has one hole and two slotted holes (adjustable). Manuals I have downloaded do not indicate which side of the frame the adjustable housing must fit to.

Q1) What is the purpose of rear main roller adjustment? It adjusts the height of the frame on one side only and effectively tilts the frame but why?

Q2) I have already assembled the rear main roller and fitted the adjustable housing to the drive chain side. Is it critical for the adjustable housing to be on any particular side?

Q3) If so what side should it be fitted to?

Hope somone can help,
Cheers, Craig.
