Where to drill the hole for flushing kit

About to install a flushing kit on my trailer but trying to work out the best place to do it as the knott 203 drum is quite tightly packed when all back together.

I was thinking around about the 10 o'clock position but would be behind a pad then.

Go for 11 o'clock, next to the adjuster. The metal i thicker an you can tap it properly.

If you go for the thinner part of the backplate you'll find that you can tap it, but only with about two threads. This will then work loose, as there's not enough 'meat' for it to grip.

I did the same for the MacRib the other day.

It's a 1/4" bsp tap. You'll need an 11mm drill, for the final hole.

I you haven't got them I'll happily drop one in you can borrow, I you're local-ish to Fareham tomorrow.

Thanks Ben

Looks like I have bought the wrong style of fitting as I was going to diy one without having to tap the backplate.
but the thickness of the plate I'm now looking at is two thick for the style I want so ill have to order some new push in fittings

As I ordered these type and should have got male version
BSP Female Thread , Metric Push Fit , Pneumatic , Water etc | eBay

And was going to secure with these

Brass BSP Reducing Bush Fitting Hex - Choose Sizes | eBay

Also just to double check before I go making Swiss cheese out my back plate

It's 11 o'clock on the starboard side wheel

And 1 o'clock on the port side wheel

Thanks again

Should be ok on the drill bit and taps as it gives me a excuse to buy more tools

You can Never have too many tools lol

You're right, you can't have too many!

Yup, that sounds good.

They may work though, if you go for the thinner part of the backplate. If I've understood correctly, you're going to drill a hole, push the male bit through the hole, from inside to out, and then screw the female part on to that? If so, I think you'll be ok. Unless there's only about 5mm of thread on the male bit?

AAAAAAAAAAAAAAAAAAAGHHHHHHHHHH!!!!!!

Another hole drilling thread!!!!!!



Joking aside, if the plate is thin, canlt you stick a nut & washer on the flush nozzle & "nut & bolt" it on? (suitable thread locking being used to stop the nut coming off)
