hi Mike i cut 19 tpi on my boxford

you need 20 t stud gear

80 t idler and 38 t on the screw

then select 28tpi on the gearbox

worked ok for me

3/8 19 tpi is pipe thread 3/8 unc is 16 tpi and drill 8.25mm

Jason I'm curious how you machined the hole in that part with the flat

Dave

after reading all the posts and following your links I'm thinking the insert is WBMT thanks to all

Dave

thanks everyone will keep looking

hi all does anybody recognise this small boring bar its made by HOYBIDE and is 6mm in diameter I'm trying to find inserts for it but haven't had any luck they are tiny

Sean don't think it matters 3/4 or 1 hp its the rpm mine has a 930 rpm 3/4 hp motor and i think its the original motor

Alan is it not BSF 1.5 inch 8 tpi same as a boxford spindle nose UNC would normally be 1 inch 8 tpi

i think the pipe your looking for is called protecta line its used in contaminated ground

hi Steve according to MSCs catalogue red is for high tensile materials yellow is general purpose and blue is for stainless and tool steels hope this helps

could you drive a wedge into the split and remove it when its back on the post

hi Mike if your radiators are old it could be rust particles going round the system maybe small ones getting past the mag filter a magnet used to stick on the copper pipes on my system before we renewed it due to the rust particles in the water

hi David

the small pulley is cast iron approx 50mm thick and vee ways measure approx 117mm large and 92 small at the largest diameter hope this is of help
