Evilchicken0 Posted February 9, 2014 Report Share Posted February 9, 2014 Bloody thing !! Ok - I have a T'Cat. It's an ex-race engine with no starter. The oil feed to the starter clutch has a bit of weld on to seal it up. So all I have to do is drill the weld out. Because the hole is close to the casing all I get to drill it is a dremmel thing, the hole is 2mm dia. I've use a 1mm and then a 2mm drill bit ... so far after an hour I have 2mm penetration (nothing funny there) - WTF Yes I am drilling in the right place. Should I be using a different type of bit or something ??? Big Pic from taking the starter clutch bolt out, I couldn't get the clutch holding tool on anything.

Simbo Posted February 10, 2014 Report Share Posted February 10, 2014 Can see where your drilling. Link to comment Share on other sites More sharing options...
Evilchicken0 Posted February 10, 2014 Author Report Share Posted February 10, 2014 See where the crank cases meet, follow that line up the crank shaft and you'll see theres a more polished area - thats where I'm drilling. The pic was taken before I started. Link to comment Share on other sites More sharing options...
kaighn80 Posted February 10, 2014 Report Share Posted February 10, 2014 Drilling into ally? Something wrong with the drill bit I should think, either blunt or being run too fast, drill bits like it slow and gentle Link to comment Share on other sites More sharing options...
Superdunc Posted February 10, 2014 Report Share Posted February 10, 2014 I think the evil one is trying to drill the welded up hole on the crank. It will be as hard as fuck, you will blunt normal HSS drill at an alarming rate, if you are lucky it might just be the outer layer of weld that is hard, and get easier.Getting the speed of the drill bit will be critical to how well it cuts, as will lots of lubricant.A cobalt tipped drill it what you'd want ideally, but if you can't get one. buy half a dozen good quality hss ones and be patient.

Evilchicken0 Posted February 10, 2014 Author Report Share Posted February 10, 2014 You're right Superdunc its drilling the weld. I've got the dremel as slow as it will go. Patient ..... but I want it now !!! Link to comment Share on other sites More sharing options...
Evilchicken0 Posted March 30, 2014 Author Report Share Posted March 30, 2014 Finally got it done. I got a flexi drill extension which just about fitted in the space for the starter gears. Went through 4 or 5 1.5mm bits and then a couple of 2mm opening it up. What a pita. Still I can get the clutch back in and of course the starter gears Link to comment Share on other sites More sharing options...
